I would never surrender and would to fight to my last breath rather than be captured.  I can tell you that if you are captured by the Taliban/AQ/ ISIS or any other terror organization you at the very least be tortured and most likely hung or beheaded.  Your torture and death will be recorded and used as propaganda. I ve seen the tapes that are distributed in Iraq and in Afghanistan and they are beyond description.
I would fight until I my last breath because the men I serve with would do the same for me.          
 
For those saying they could not fight for oil, corporate interests, Exxon, etc... BS. If you need to tell yourself that to feel better or justify something ok but at least keep that to yourself.
You fight for the person next to you. You fight because you believe there is evil in the world. If you doubt the evil, you have no idea what happens to women and children in Iraq, Afghanstan, Syria, etc... its pure evil nothing else can explain it and I'll would do anything to stop that evil from reaching our shores.
